Move the runtime info specific to display into display-specific
structures as has already been done with the constant display info.

v2:
 - Rename __runtime to __runtime_defaults for more clarity on the
   purpose.  (Andrzej)
 - Move introduction of DISPLAY_INFO() to previous patch.  (Andrzej)
 - Drop NO_DISPLAY macro.  (Andrzej)
v3:
 - Use "{}" instead of "{ 0 }" for empty struct init.  (Jani)
